Objective: Subjects with migraine headache often have stiff posture, especially in the head and neck. Also, these patients often have reduced cervical range of motion, faulty posture, forward head posture, increased sensitivity on the cervical muscles, and myofascial pain syndrome. Myofascial Trigger Points (MTrPs) are considered as the contributing factors to migraine headache. They produce pa...
To examine the effects of L-arginine (L-Arg) on endothelial function, we administered 0.5 g/L L-Arg in drinking water to deoxycorticosterone acetate (DOCA)-salt rats for 8 weeks and then measured nitric oxide (NO) release from isolated kidneys using a newly developed real-time chemiluminescence method. Renal pathology was also analyzed. Acetylcholine caused much smaller declines in renal perfus...
BACKGROUND Nitric oxide donors are widely used to treat cardiovascular disease, but their major limitation is the development of tolerance, a multifactorial process to which the in vivo release of nitric oxide is thought to contribute. Here we describe the preclinical and clinical results of a translational drug development effort to create a next-generation nitric oxide donor with improved pha...
BACKGROUND Ischemic preconditioning protects the heart against subsequent ischemia. Opening of the adenosine triphosphate-sensitive potassium (KATP) channel is a key mechanism of preconditioning. Ketamine blocks KATP channels of isolated cardiomyocytes. The authors investigated the effects of ketamine and its stereoisomers on preconditioning. METHODS Isolated rat hearts (n = 80) underwent 30 ...
ایندومتاسین 1-(p-chlorobanzoyl)-5-methoxy-2-methyl indole-3-acatic acid یک داروی ضد التهاب غیر استروئیدی (nsaid) است . نیمه عمر آن 4ˆ5 ساعت بوده و حداکثر 200 میلی گرم از آن در روز در دوزهای منقسم موارد مصرف متعددی دارد و از جمله در درمان بیماریهایی مانند آرتریت روماتوئید، استئوآرتریت و نقرس بکار میرود. طولانی بودن مدت مصرف دارو و بروز عوارض جانبی گوارشی از مشکلاتی هستند که بیماران مصرف کننده با...
BACKGROUND Adult respiratory distress syndrome is often refractory to treatment and develops after entering the health care system. This suggests an opportunity to prevent this syndrome before it develops. The objective of this study was to demonstrate that early application of airway pressure release ventilation in high-risk trauma patients reduces hospital mortality as compared with similarly...
Background: Arterial pressure is one of the most important physiological variables and often needs to be monitored repeatedly or continuously in perioperative period. Arterial pressure monitoring is one of the standard monitoring in operating room. During general anesthesia, blood pressure can be measured by using a noninvasive arterial pressure method or continuous invasive arterial pressure b...
PURPOSE Postoperative release of scleral flap closure suture is useful in trabeculectomy combined with cataract surgery. We determined risk factors for early filtration failure requiring suture release during the first month after primary glaucoma triple procedure. METHODS The medical records of 71 consecutive patients with primary open-angle glaucoma who underwent a primary glaucoma triple p...
Increasing renal pelvic pressure increases afferent renal nerve activity (ARNA) by a prostaglandin E2 (PGE2)-mediated release of substance P (SP) from renal pelvic sensory nerves. We examined whether the ARNA responses were modulated by high- and low-sodium diets. Increasing renal pelvic pressure resulted in greater ARNA responses in rats fed a high-sodium than in those fed a low-sodium diet. I...
Airway pressure release ventilation (APRV) is inverse ratio, pressure controlled, intermittent mandatory ventilation with unrestricted spontaneous breathing. It is based on the principle of open lung approach. It has many purported advantages over conventional ventilation, including alveolar recruitment, improved oxygenation, preservation of spontaneous breathing, improved hemodynamics, and po...
